SONAR’s status bar displays bold letters to indicate when Caps Lock, Scroll Lock, Pause and Num

Lock are enabled.

Reduce GUI updates to improve playback performance

SONAR has a CPU conservation mode that reduces the number of GUI updates with no effect on

actual playback quality and rendering. This maximizes CPU resources for the audio engine and can

be useful while playing projects that consume a lot of CPU, to help avoid dropouts.

Like the Scroll Lock key, the Pause key now works as a special GUI throttle toggle key. When the

Pause key is pressed, SONAR runs in a CPU conservation mode by reducing the frequency of GUI

updates. For example, VU meter updates, Now position pointer and progress updates will appear to

update less frequently.

During CPU conservation mode, the UI is only updated once per second.

This mode can also be helpful to conserve CPU while doing a real-time bounce (see “Real-time

bounce” on page 666).

Note: If you experience a dropout or your CPU or Disk meters are reading high, there are steps

you can take to improve your audio performance. For more information, see “Dropouts and
